JetProg - multiprogramming system

Discontinued product. Replacement: Elnec Multiprogramming systems.

MCS-51 series microcontrollers multiprogramming

Short description:

  • MCS-51 series microcontrollers multiprogramming solution based on the JetProg programmer
  • supports MCS-51 microcontrollers up to DIL40(PLCC44)
  • programs up to 8 devices simultaneously
  • available submodules for different packages
  • true low voltage support down to 1.8V
  • high throughput
  • comfortable control program, MS Windows (95/98/Me/NT/2000/XP) compatible

MCS-51 series microcontrollers multiprogramming system comprise of



  • The Common multiprogrammimng module no.1 with MCS51 socket submodules present - attached to JetProg programmer - high throughput manual operated MCS51 microcontrollers multiprogramming solution, suitable for medium volume production application.
  • This MCS-51 series microcontrollers multiprogramming system provides very competitive price but excellent hardware design for reliable programming.


  • The MCS-51 series microcontrollers multiprogramming system supports MCS51 compatible microcontrollers of various manufacturers, based on both EPROM and Flash technology.
  • The replaceable socket submodules package enable different package type support.
  • Optimized advanced pindriver deliver programming performance without overshoot or ground bounce for all memory technologies. Pin drivers operate down to 1.8V so you'll be ready to program the full range of today's advanced low-voltage devices.
  • The MCS-51 series microcontrollers multiprogramming system performs programming verification at the marginal level of supply voltage, which, obviously, improves programming yield, and guarantees long data retention.


  • The MCS-51 series microcontrollers multiprogramming is driven by an easy-to-use WIN-95/98/2000/XP compatible control program with pull- down menu, hot keys and on-line help. Selecting of device is performed by its class, by manufacturer or simply by typing a fragment of vendor name and/or part number.
  • Standard device-related commands (read, blank check, program, verify, erase) are boosted by some test functions (insertion test, signature-byte check).
  • All known data formats are supported. Automatic file format detection and conversion during load of file.


Multiprogramming modules

Common multiprogramming module no.1

  • advanced specialized pindriver (8x), compatible for multiprogramming of more chip types (EPROM/EEPROM, MCS51, PICmicro, ...)
  • pindrivers are independent, therefore defective chip haven't influence to another programmed chips
  • perfect ground and necessary supply/programming voltage can be applied independently to each socket of submodule
  • current limitation for each socket, overcurrent shutdown, power failure shutdown
  • banana hole for ESD wrist straps
  • insertion test
  • ord. no.: 70-0151 (discontinued)
